Pull Request Overview

This PR refactors the neural network XML formatting code by extracting functionality into separate modules and reorganizing the training pipeline. The changes improve code organization and modularity while adding new formatting capabilities.

• Refactored monolithic train_from_xml.py into modular components
• Created new LSTMFormatter and XmlOperations classes in dedicated modules
• Added a separate format_xml.py script for model inference/formatting tasks
